BIOLOGY 6TH EDITION(BROOKER ET AL., 2023) CHAPTER 1 WITH EASY
QUESTIONS AND ACCURATE ANSWERS
1. Atom: the smallest un it of an element that has the chemical properties of an
element, all matter is composed of atoms
2. molecule/macromolecules: atoms bond with each other to form
molecules. a polymer is many molecules bonded together and is called
a macromolecule
3. cells: The simplest unit of life surrounded by a membrane and containing
molecules and macromolecules.
4. tissues: in multicellular organisms many cells of the same type associate
with each other to form tissues
5. organs: an organ is composed of many types of tissue
6. Organism: all living things can be called organisms, they are classified
into species.
7. Species: A group of similar organisms that share distinctive form and set of
attributes in nature, they are closely related genetically so can breed and
produce fertile ottspring.

QUESTIONS AND ACCURATE ANSWERS
8. Population: a group of organisms of the same species that occupy the
same environment
9. community: an assemblage of populations of ditterent species, the
type of species is determined by the environment and interactions with
other species
10. ecosystem: formed by interactions of a community of organisms
with the physical environment
11. biosphere: includes all the places on earth where organisms exist.
life is found in the air, bodies of water and on land, within the soil as well
12. Evolution: the diversity of life evolved over time by processes of
mutation, natural selection and genetic exchange
13. structure and function: basic units of structure define the
function of living things
14. information flow, exchange and storage: the growth and
behaviour of organisms are acti-vated through the expression of genetic
